The article was kind of vague. There are a lot of different factors to consider before one should take children away from everything they know. They were in a monitored facility where food was controlled, but how strict was it? I mean even if someone is eating nothing but healthly home-cooked meals but they don't have the appropriate portions, he or she won't really see an improvement (unless its all raw fruits and vegetables, but I highly doubt that was their primary diet). I don't know about anywhere else, but in the United States, truly healthy food is NOT inexpensive. It is near impossible for a lower-income family to get proper nutrition. Even if the government gives you food, theyre mostly vouchers for junky foods.
